Title (EN) SWITCH WITH INDUCTOR FUNCTION
(FR) COMMUTATEUR A FONCTION DE BOBINE D'INDUCTANCE
Abstract:
(EN) The invention relates to an inductive component having a relay and inductor function. According to the invention, one and the same magnetic circuit is used for both the relay and the inductor function. The inductive component includes a fixed part (22, 32, 52) and a movable part (21, 31, 51) with an air gap (24, 44, 53) therebetween, and further includes a coil having two windings. The first winding is adapted to receive a strong current and therewith attract the movable part towards the fixed part, therewith providing the relay function, whereas the other winding is adapted to receive a weak current that will not influence the position of the movable part, such as to provide the inductor function.
(FR) L'invention concerne un composant inductif possédant une fonction de relais et une fonction de bobine d'inductance. Selon l'invention, on utilise un seul et même circuit magnétique à la fois pour la fonction de relais et pour celle d'inductance. Le composant inductif comprend une partie fixe (22, 32, 52) ainsi qu'une partie mobile (21, 31, 51) avec un espace à air (24, 44, 53) entre ces deux parties, et il comporte en outre une bobine présentant deux enroulements. Le premier enroulement est conçu pour recevoir un courant fort et attirer à l'aide de celui-ci la partie mobile vers la partie fixe, exécutant ainsi la fonction de relais, tandis que l'autre enroulement est conçu pour recevoir un courant faible qui n'agit pas sur la position de la partie mobile, exécutant ainsi la fonction de bobine d'inductance.
